Clip Description

Tropical rainforests are found near the equator in hot, wet regions called the tropics. It has been estimated that more than half of the world’s plant and animal species live in tropical rainforests. Scientists believe that many of these species have not yet been discovered.

In this fascinating clip, we journey deep into the Amazon rainforest in South America. We learn that this rainforest has a greater variety of life than any other forest on the planet. Which mammals, birds, reptiles, amphibians and insects do you think we’ll see in the clip? Watch the clip to find out.

Quick Whiteboard Challenge

In the clip, lots of numbers are mentioned that relate to animal numbers.
